The GEMINI Model-4 is a unique product that is two devices in a single chassis. It includes both a high-performance power conditioner and an advanced ground noise reduction hub. It features patented NIC™ noise isolation chamber technology that provides a common grounding point for all components and extends the GEMINI’s noise reduction capabilities to all system components. This significantly reduces AC noise and voltage differences between chassis components which may help to reduce potential ground loops.

The GEMINI Model-4 is the perfect solution for simpler high-end systems, headphone systems, and for network closets. Headphones are particularly sensitive to power line noise and ground plane noise. Network switches, routers, music servers, and computers all respond positively to improved power distribution and ground plane noise reduction. A GEMINI in the network closet provides a very significant performance boost to any audio/video system. Although the GEMINI Model-4 has a small footprint, it is a high-current device capable of powering 200+ watt amplifiers.

For larger systems with more than 4 components please refer to the Gemini Model-8.
